I prefer to use something like Nat Geo "Topo!" Up front cost but I print my own out on the same paper for about $1 per sheet. I print on 8.5x14 and I print double sided. I can put my own markings on the map in the software, it will tell me about how long the hike is and will print an elevation profile.
Out here the elevation lines are 40 ft., there area lot more of them and they are a lot closer together.
Looks like that last video is gone. "This video has been removed by the user"
